//! Cli8 64-case integration matrix — 4 verbs × 4 wrappers × 4 status outcomes.
//!
//! Built per dispatch §2.8 + omnibus §2.1 (the BD day-1 scope: 4 mgrs not 6).
//! Each case is parameterised via a small driver below; on assertion failure
//! we print `(verb, wrapper, status)` so the cross matrix is triage-able.
